How often should the coolant be replaced in a Hyundai Elantra?
1 Answers
Modern Elantra coolant generally needs to be replaced every 2 years. The function of coolant is to prevent the cooling liquid from freezing into ice when the vehicle is turned off in cold winter, which could cause the radiator and engine cylinders to crack. In fact, coolant should be used not only in winter but also in other seasons. Coolant is composed of more than 95% ethylene glycol. Compared with ordinary water, ethylene glycol is more freeze-resistant, has a higher boiling point, less volatility, and higher stability, making it an ideal material for coolant. The purpose of cooling liquid is to carry away the heat generated when the engine cools down, and it is an indispensable component for engine operation.
